Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

(1,2,3,4)(5,6,8,9)(7,11,12,10)(15,17)(19,20)(22,27)(24,28);(6,9)(10,11)(13,14,18,16)(15,19,17,20)(21,22,26,27)(23,28,25,24);(5,6)(7,10)(8,9)(11,12)(13,15,18,17)(14,19,16,20)(21,23,26,25)(22,28,27,24);(1,2)(3,4)(5,7,8,12)(6,10,9,11)(13,16,18,14)(15,20,17,19)(21,24)(22,23)(25,27)(26,28);(5,6)(7,11)(8,9)(10,12)(13,17,18,15)(14,20,16,19)(21,25,26,23)(22,28,27,24)
